Configuration fails while compiling BoringSSL

Summary

Cmake fails to configure the build (GCC 15.2) due to a compilation error during BoringSSL:

make[3]: warning: -j8 forced in submake: resetting jobserver mode.
In file included from /xxx/.hunter/_Base/15ca502/2341084/9613f97/Build/BoringSSL/Source/crypto/fipsmodule/bcm.c:31:

      |          ^~~~~~
cc1: all warnings being treated as errors
make[5]: *** [CMakeFiles/fipsmodule.dir/build.make:79: CMakeFiles/fipsmodule.dir/crypto/fipsmodule/bcm.c.o] Error 1

This is GCC 15.2.1, which defaults to gnu23, which imposes memchr() and others should return const pointers when passed arguments are const -- then compilation fails due to -Werror.

Expected behavior

The project would configure without problems.

Actual behavior

The project doesn't configure properly.

Relevant log output

Possible Solution

The proper solution is BoringSSL upstream fixing their codebase to C23; or upstream properly setting -std=c17 or whatever they're using; or simply removing -Werror=discarded-qualifiers.

A workaround is to set -Wno-error=discarded-qualifiers during the build of this particular dependency, but I'm not sure how to do it with this Hunter thing. Any help is appreciated.

Version

v0.1.37

Would you like to work on fixing this bug ?

Maybe

Reproduce la configuración de CMake con GCC 15.2.1 e inspecciona cómo Hunter construye la dependencia BoringSSL, especialmente el fallo reportado en internal.h y los flags de advertencia. Se considera terminado cuando el proyecto se configura correctamente sin el error «discarded-qualifiers».
